Summary: | [Purpose] We conducted a clinical investigation comparing surgical cases of pheochromocytoma with other cases of adrenal tumor.[Subjects and Methods] We examined retrospectively 57 patients with adrenal tumor who underwent surgery in our department from April 2010 to August 2015. Cases were classified into 17 cases of pheochromocytoma and 40 cases of other adrenal tumors. The two groups were compared in terms of factors such as sex, surgical methods, and tumor size. Patients who underwent laparoscopic surgery were classified as pheochromocytoma cases and other adrenal tumor cases, and were compared regarding factors such as operating time, blood loss, and length of hospital stay. All cases of pheochromocytoma were classified into cases requiring use of a vasopressor immediately after surgery and cases not requiring a vasopressor, and these groups were compared regarding preoperative levels of catecholamines.[Results] The mean age of patients with pheochromocytoma was 53.4 years, and thise group comprised 9 men and 8 women. Mean tumor size of the pheochromocytoma was 4.03 cm, significantly larger than that of other adrenal tumors (P < 0.0001). Regarding surgical methods,13 laparoscopic and 4 open procedures were performed. Mean operating time of laparoscopic surgery was 182.2 min, significantly longer than that of the other adrenal tumor group (P = 0.0061). The group requiring postoperative use of a vasopressor had a significantly higher preoperative urinary noradrenaline level (P = 0.0018) than the group not requiring vasopressor.[Discussion and Conclusion] The longer operating time in laparoscopic surgery for pheochromocytoma was attributed to changes in blood pressure and large tumor size. Patients requiring postoperative use of a vasopressor had higher preoperative levels of blood and urinary noradrenaline, and urinary vanillymandelic acid. These higher levels were considered predictive of need to use a vasopressor postoperatively.
【目的】 褐色細胞腫の手術症例について,他の副腎腫瘍と比較し臨床的検討を行った。【対象と方法】 2010年4月から2015年8月までに当科で手術を行った副腎腫瘍57症例を対象とした。17例の褐色細胞腫症例と他の副腎腫瘍症例40例の二群に分け,性別,手術術式,腫瘍径などを比較検討した。また,腹腔鏡下手術を行った症例に限定し,褐色細胞腫症例と,他の副腎腫瘍症例に分け,手術時間,出血量,入院期間等に関して比較検討した。さらに褐色細胞腫症全例において術直後から昇圧剤を必要とした群と,必要としなかった群に分け術前の各種カテコラミン値を比較した。【結果】 褐色細胞腫例の平均年齢は53.4歳,男性9例,女性8例であった。腫瘍径の平均値は4.03 cmであり,他の副腎腫瘍径より大きかった(P < 0.0001)。手術術式は腹腔鏡下手術が13例,開放性手術が4例であった。出血量は褐色細胞腫例で有意に多く(P = 0.0021),ヘモグロビン値の低下についても褐色細胞腫例で高かった(P < 0.0001)。腹腔鏡下手術例では手術時間は平均182.2分でありその他の副腎腫瘍より長かった(P = 0.0061)。術後に昇圧剤を必要とした褐色細胞腫症例において昇圧剤を必要としなかった症例に比べ,術前の血中ノルアドレナリン値,尿中ノルアドレナリン値,尿中VMA値が有意に高かった(P = 0.0237,P = 0.018,P = 0.0052)。【考察・結論】 褐色細胞腫の腹腔鏡下手術では手術時間は長く血圧の変動や,大きい腫瘍径が関係していると考えられた。術後に昇圧剤を必要とした症例は,術前の血中・尿中ノルアドレナリン,尿中VMAが高く,これらの値は術後に昇圧剤使用を必要とする予測因子となると考えられた。 |
